I had a look at the data and something rather strange is going on with your data!
I'm thinking there might be something wrong with your settings in Regim with regards to the debayering matrix you're using. Some channels may be swapped.
I would also strongly suggest you apply dithering (if possible) next time - there is a lot of pattern ("walking"/"streaking") noise visible.
Do let me know how you get on!
